【问题描述】：

我正在测试一个测试用例。我验证了 MongoDB 方法，它们似乎符合日期。 GitHub 上也没有未解决的问题。

Error:    at MongoMemoryServer.getUri (node_modules/mongodb-memory-server- 
          core/src/MongoMemoryServer.ts:706:15)
          at src/test/setup.ts:7:32
          at src/test/setup.ts:8:71
          at Object.<anonymous>.__awaiter (src/test/setup.ts:4:12)
          at Object.<anonymous> (src/test/setup.ts:5:22)   



import { MongoMemoryServer } from "mongodb-memory-server";
import mongoose from "mongoose";

let mongo: any;
beforeAll(async () => {
  mongo = new MongoMemoryServer();
  const mongoUri = await mongo.getUri();
  await mongoose.connect(mongoUri);
});

beforeEach(async () => {
  const collections = await mongoose.connection.db.collections();
  for (let collection of collections) {
    await collection.deleteMany({});
  }
});

afterAll(async () => {
  await mongo.stop();
  await mongoose.connection.close();
});

标签： mongodb jestjs

【解决方案1】：

将行 mongo = new MongoMemoryServer(); 更改为 mongo = await MongoMemoryServer.create()

【讨论】：

我想这条线不见了 - “await mongo.start()”

【解决方案2】：

     Changing await mongoose.stop()to await mongoose.disconnect()

      worked for me
